Family Nurse Practitioner Exam

Which of the following symptoms is not considered a criterion for diagnosing autistic disorder according to DSM-5?

1. Onset of symptoms before age 3 years

2. Lack of social interaction or social reciprocity

3. Stereotyped and repetitive movements such as hand flapping

4. Depressed affect

The correct answer is: Depressed affect

The choice indicating "depressed affect" is not considered a criterion for diagnosing autistic disorder according to DSM-5 is accurate because the criteria for autism spectrum disorder focus on specific characteristics related to social communication, restricted interests, and repetitive patterns of behavior rather than mood disorders. The DSM-5 outlines that symptoms must include deficits in social communication and interaction, as well as restricted or repetitive behaviors. Onset of symptoms before age 3 years is crucial as it establishes the early developmental nature of autism. The lack of social interaction or social reciprocity pertains directly to the challenges individuals with autism often face in social settings. Stereotyped and repetitive movements, such as hand flapping, are also commonly recognized behaviors associated with autism. Therefore, while depressed affect may occur in individuals with autism, it is not a diagnostic criterion according to the DSM-5.
